Multiquip 42974 Fitting 90 Degree 16 MOR x 12 MORFS - OEM Replacement Part

This 90-degree hydraulic fitting connects critical hydraulic lines in the STX6H ride-on trowel's hydrostatic system, which holds 8 gallons of hydraulic fluid and powers both the drive and steering functions. The 16 MOR (male O-ring) x 12 MORFS (male O-ring face seal) configuration ensures leak-free connections in high-pressure hydraulic circuits that control blade pitch, trowel speed, and steering response.

Hydraulic fittings are common failure points during routine maintenance, system troubleshooting, or when replacing hydraulic components like pumps, motors, or cylinders. The STX6H's hydraulic system requires proper fittings to maintain correct operating pressures for pitch control and stroke cylinder calibration. Any hydraulic leaks or damaged fittings can affect blade pitch pressure, trowel speed adjustment (30 ± 3 RPM specification), and overall machine performance during concrete finishing operations.

This fitting is essential for technicians performing hydraulic repairs, secondary hydraulic fill procedures, or pressure adjustments as outlined in the STX6H setup and calibration manual. Replace damaged or leaking fittings immediately to prevent hydraulic fluid loss and maintain proper system pressure.
